Convection oven doesn't heat


Possible that the relay is faulty or there is fault on the control panel. It can also be related to problems on the thermocouple or sensors which can cut off prematurely the element.

Tappan Oven 316246653. Preheating the Oven does not work. Bottom Heating Coil (if thats what its called) is not working. The Broiler Coil at the Top does work. Is it the bottom coil that needs replaced...


Usually when the element fails to heat up, It means its usually broke, cracked, or where they plug in gets brittle and breaks. Your best bet is to replace the bottom element.

Microwave runs but doesn't heat. Can we replace the heating element ourselves?


There are no heating elements in a normal Microwave Oven: instead, an extremely dangerous High Voltage and Amperage Magnetron is used and its replacement is not considered safe for the average handyman!
Check if your unit is still under warranty and if so, take it to an approved warranty appliance repairer as directered by the manufacturer or supplier.
In any case, nowdays, the high cost of a replacement Magnetron (if you can find one) is usually more than the cost of a new equivalent Microwave oven.

Hope it helps!

I have a Black 4 cup Mr Coffee with luminate lighting and time display programer so that I can have coffee brewed in the morning when I get up for work at 4:30am my problem is the coffee pot has started...


I had a black and decker coffee pot do same thing and it was brand new. here is how I fixed it.
make sure the filter seated down good. If you look at the top of the coffee pot it should open up the little valve of the coffee filter holder. also mine had a little water spout above the coffee filter that swings over the filter. make sure it is over the filter. I know my coffee pot is different, but I think the problem is the opening from filter to coffee pot is not open some how so the water is flooding over the filter and going out the sides onto counter
hope this helps

The microwave timer runs but turnable plate doesn,t rotate and the heating elements doesn't comes on


you need a new microwave. There are no heating elements in mocrowaves just micro-waces. It only heats moisture it does not heat objects. It is to dangerous to replace the actual device that heats liquids.

How do I remove the waffle grate plates from my Waring Waffle Pro? Can't find my manual.--Frank Davis


Hi,
Here is how you need to replace or bring out the plates.

Make sure you are unplugged from the wall before doing anything or you will get shocked. You do not need to take the bottom cover off the base. You do not need to take the top plate apart (they super glued one screw in the top plate (lid), you'll strip out the screw head trying to remove it anyhow). All you need to open is the bottom plate, it has 4 screws in it you will see when you open the lid, these screws are not super glued and will come out. 2 on each side in the back, 2 in the center of the front, long screws go in the back, short in the front.

There are 2 white wires, 1 black wire, 1 green wire that run up the neck of the waffle maker to heat the top and bottom heating elements. The 2 white wires are neutral, the green wire is a ground, the black wire is power.

This black wire runs from the electronic control board in the base of the unit, up the neck in the rear, through a thermal fuse, to the bottom element then jumps up to the top element. All you need to take apart is the bottom plate, the part you pour the batter into. It has 4 screws you will see when you open the top plate up, take those out and you are going to find the black wire is covered by a white rubber like tube about 3 inches long. In the center of this rubber insulation there is a metal clip with a single screw. Take that screw out, pull off the metal clip and slide (don't cut) the rubber like insulation back.

You will find the black wire is crimped onto a silver metal bullet looking component. This component is called a "thermal fuse", its designed to fail at 240 degrees C. Its obviously a design flaw and the thermal fuse is under rated for the actual heat within the device. Its also a one shot fuse, so when it blows it kills power on the black wire from going to the top and bottom plates, thus no heat. It is not resettable.

I didn't even cut mine out (Waring is very skimpy with their wire, they don't leave you even a hint of extra wire to work with). I just tightly twisted the bare metal wire on each side of this component like a bread tie leaving the blown fuse in place. Then be sure to slide the rubber like insulation back over all of the bare metal so it is covering the black wire on both sides. If you don't it will short out and blow your house circuit breaker when you turn it on.

This thermal fuse was probably a requirement of the UL Listing. Its over kill, everything in there is metal so if it over heats in that area there is nothing flammable to burn. If a run away temperature occurs the wire itself will melt, short out and trip your house breaker. There are stacks of these units brand new with this same problem anyone reading this is having, the thermal fuse is under rated, the fix is simple
